Abstract Background: Postoperative pneumonia is a major cause of postoperative mortality after esophagectomy. Preoperative oral hygiene care is reportedly effective to prevent pulmonary complications after esophagectomy. Methods: Since April 2012, we have included preoperative oral hygiene in the standard perioperative care regimen for esophagectomy and have accumulated data on 188 consecutive patients undergoing esophagectomy to evaluate oral hygiene care’s effectiveness. To determine basic (i.e. non-clinical) and clinical effects of preoperative oral care, we prospectively observed the incidence rate of postoperative pneumonia and accumulated perioperative culture study and oral bacteria count data on these 188 patients. One hundred five patients studied in our previous retrospective study from 2009 to 2012 were enrolled as a historical control.Results: In the current study’s patients, no significant reduction of postoperative pneumonia was observed compared to the historical control (30 out of 188 vs. 21 out of 105, P=0.423). Perioperative culture studies showed significantly decreased positivity in preoperative oral samples (11% in dental plaque and 13% in tongue coating) but no such decrease was observed in studies of postoperative gastric juice and endotracheal sputum. With the exception of postoperative endotracheal sputum, perioperative cultures had few of the pathogenic microbes identified in pneumonia patients. In the analyses of oral bacterial count, oral microbial flora were significantly decreased after oral care in both dental plaque (median ratio to before care: 1:0.13, P<0.0001) and tongue coating (median ratio: 1:0.015, P<0.0001); however, only in the dental plaque did the decrease last until the day of the operation (median ratio: 1:0.10, P=0.0008). Logistic regression analysis showed only the bacterial amount in dental plaque on the operation day (P=0.026) to be marginally correlated to the incidence of pneumonia. Conclusions: Although perioperative oral hygiene care had a significant impact on oral bacterial load, its contribution to the prevention of postoperative pneumonia was limited.Trial registration: This study was registered and approved by the institutional review board of The University of Tokyo Hospital: Approval number: 3383, Date: 26th November, 2011

To estimate the amount of bacteria present in patients wearing metallic and ceramic brackets. The objective of the present study is to investigate the amount of bacteria in patients wearing fixed orthodontic appliance. The fixed orthodontic appliance is the treatment of conditions like malocclusion. It includes brackets, tubes, band and ligating materials and archwires. Composite is used for bonding the brackets to the teeth surface, and it also induces the formation of plaque. Dental plaque is the main aetiology for Causing gingivitis. This study shows that the metallic and ceramic brackets worn by the patients were contaminated with various microorganisms. The main focus of the study is to create awareness among patients with fixed orthodontic appliance and to improve their oral hygiene and to prevent periodontal problems.

Consider that The Great Barrier Reef is home to thousands of species of plants and animals with spatiotemporally predictable fish communities on coral reefs, and compare this with the fact that human oral bacteria develop spatiotemporally predictable dental plaque communities on enamel after each oral hygiene procedure. This reassembling of oral bacterial communities over a time interval of only a few hours offers an opportunity to investigate the role of communication in community architecture and composition.

Background Frequent use of mouthwash (MW) is one of the most effective methods used to prevent oral bacterial infections and to assist individuals in their efforts to achieve and maintain better oral health. Using a MW containing antibacterial agents would be a simple way to prevent growth and multiplication of pathogenic organisms in oral cavity causing dental caries and other mouth diseases. Chlorhexidine (CHX) and Hexetidine (HX) have been proposed as potent biocides against oral bacteria. Objective The present study was performed to investigate oral bacteria growth inhibition when using any of four mouthwashes that are commercially available in the Libyan market and contain either CHX, (Zordy land Oraxin), or HX, (Hextril and Givalex), and to clarify whether CHX and HX were suitable and safe biocides that can be included in mouthwash products. Materials and Methods Sixty adult (45 females and 15 males) volunteers had been chosen and divided into four groups and their saliva samples were assessed for microbial count at the beginning and the end of two weeks of treatment, during which they rinsed with 15ml of mouthwashes for 30 seconds twice a day (morning and evening) in addition to their usual oral hygiene procedures. The antibacterial activity of mouthwashes was assayed by cell viable count technique and cell diffusibility measurement. Results The results showed wide variations in the effectiveness of mouthwashes; those containing CHX were more effective (P ≤0.05) than formulations containing HX on oral microbial count. The main findings of the present study were that Zordyl, Oraxinand Hextril exerted high effects on the salivary microbiota, causing 90%, 60% and 34% reduction in salivary bacterial counts respectively. 25% reduction was observed for Givalex. On the other hand, the zone of inhibition test showed that Zordyl and Oraxin had large zone inhibitory effects, while Hextril and Givalex, were less effective on some bacterial species. Conclusion It can be concluded that twice daily use of CHX mouthwash (CHX-MW) or HX mouthwash (HX-MW) reduces oral bacterial load counts in healthy subjects when used as an adjunct to their normal oral hygiene procedures. This also suggests that inhibitory power of mouth washes containing CHX is greater on oral bacteria than mouthwashes containing HX.

Mechanical plaque control appears to be the primary means of controlling supragingival dental plaque build-up. Although daily oral hygiene practices and periodic professional care are considered the basis for any program aimed at the prevention and treatment of oral diseases, these procedures are technically demanding, time consuming and can be affected by the compliance and manual dexterity of the patient. Individual skills and acquired behavior patterns determine effectiveness of a preventive program and oral hygiene practice. Successful preventive programs and home care procedures clearly depend on the interaction and commitment between the dental professional and the patient. Identifying the capacity of the individual to comply with the professional recommendations and evaluating the dexterity of the patient to remove supragingival dental plaque will permit the implementation of an adequate preventive program and can help on the selection of adjunctive antimicrobial agents and devices needed to reach an effective oral care routine.

Exciting Time

Pregnancy is a unique, exciting time in a woman's life, and there are so many changes going on in human body during pregnancy and mouth is no exception , so good oral hygiene is extremely important during pregnancy . Usually oral health is often the most neglected form of health during all stages of life & the most important cause for this neglection is lack of awareness among people & this problems also increases when a lady is pregnant because of mis-perceptions and mis-leading information in the society or due to lack of knowledge. But the fact is during pregnancy many complex physiologic changes occur in the women’s body, which can adversely affect oral health and in turn those oral health problems may lead to pregnancy outcomes like preterm birth or low birth weight. Proper oral care is of utmost importance during pregnancy to avoid these complications. Avoiding foods that may cause oral problems, proper brushing and flossing and having dental consultations on a regular basis are steps to ensure good oral health during pregnancy.

The aim of this study was to evaluate the potential anti-biofilm and antibacterial activities of Streptococcus downii sp. nov. To test anti-biofilm properties, Streptococcus mutans, Actinomyces naeslundii, Veillonella parvula, Fusobacterium nucleatum, Porphyromonas gingivalis, and Aggregatibacter actinomycetemcomitans were grown in a biofilm model in the presence or not of S. downii sp. nov. for up to 120 h. For the potential antibacterial activity, 24 h-biofilms were exposed to S. downii sp. nov for 24 and 48 h. Biofilms structures and bacterial viability were studied by microscopy, and the effect in bacterial load by quantitative polymerase chain reaction. A generalized linear model was constructed, and results were considered as statistically significant at p < 0.05. The presence of S. downii sp. nov. during biofilm development did not affect the structure of the community, but an anti-biofilm effect against S. mutans was observed (p < 0.001, after 96 and 120 h). For antibacterial activity, after 24 h of exposure to S. downii sp. nov., counts of S. mutans (p = 0.019) and A. actinomycetemcomitans (p = 0.020) were significantly reduced in well-structured biofilms. Although moderate, anti-biofilm and antibacterial activities of S. downii sp. nov. against oral bacteria, including some periodontal pathogens, were demonstrated in an in vitro biofilm model.

To perform a systematic review of the literature on the control of oral biofilms and the incidence of nosocomial pneumonia, in addition to assessing and classifying studies as to the grade of recommendation and level of evidence. The review was based on PubMed, LILACS, and Scopus databases, from January 1st, 2000 until December 31st, 2012. Studies evaluating oral hygiene care related to nosocomial infections in patients hospitalized in intensive care units were selected according to the inclusion criteria. Full published articles available in English, Spanish, or Portuguese, which approached chemical or mechanical oral hygiene techniques in preventing pneumonia, interventions performed, and their results were included. After analysis, the articles were classified according to level of evidence and grade of recommendation according to the criteria of the Oxford Centre for Evidence-Based Medicine. A total of 297 abstracts were found, 14 of which were full articles that met our criteria. Most articles included a study group with chlorhexidine users and a control group with placebo users for oral hygiene in the prevention of pneumonia. All articles were classified as B in the level of evidence, and 12 articles were classified as 2B and two articles as 2C in grade of recommendation. It was observed that the control of oral biofilm reduces the incidence of nosocomial pneumonia, but the fact that most articles had an intermediate grade of recommendation makes clear the need to conduct randomized controlled trials with minimal bias to establish future guidelines for oral hygiene in intensive care units.
